Hello... hope all is well people, I thought I'd just update ev1 on the kinda yields you can expect from envirolights.

I used feminised Orange Bud seeds from Dutch Passion. I grew 5 plants, soon as the seeds germinated I vegged them for 4wks using cfl's, they were about 1ft tall before they were put into bloom. For flowering I used 2 x 200w red envirolights. After 2wks in flower I started using Canna bloom nutes with every watering which was every 2 or 3 days. Originally I intended to use 400w hps to flower but this was way too hot (>50C) for my wardrobe. Temp stayed steady around 25-30C using enviros.
I did have some probs with 3 plants, they started growing balls after wk 4 but i snipped these off and they were ok for the rest of the grow - i got about 3 immature seeds in my harvest. I flowered for 9wks before I chopped all 5 down. They did turn into quite tall ladies and I did start running out of height/space but luckily by using enviros they weren't heat stressed too much.
My final yield after drying them out was approx 3.5oz's. They look like they would weigh more in terms of mass but I guess they're like those fluffy kinda buds! A very nice smoke tho... heavy stone to the head and body for the first 40mins or so... and then this dies down and you're left with a nice body stone for the next hour or so.

All in all i'm not too impressed with the yield but the quality is good... my next bloom is on its way with 9 orange bud plants this time, more like a SOG method... hopefully I get a better yield this time!

Yup - similar to my experience of enviro grows. To be fair though, the smoke was always good - but the yield is nothing compared to HPS.

Will u be switching to a 250w hps now?

arfy_aiii. nice one for the yield report! i am growing 6 skunk #11 under one 125W envirolite. i will then use a single 200W flowering envirolite. i know its hard to guess, but considering your experience with envirolites what you reckon i will be able to "collect" in terms of yield? would 4 to 5 oz be a crazy estimate from all plants....??? sorry for my ignorance but when you mean "yield" that means just buds???? thanks

I have grown using 400w HPS before in my old house and with just 3 plants I had atleast 5oz's dry of bud which was quite good for my novice growing skills but this was two years ago. I would love to go back to hps but I reckon the 250 hps would still produce too much heat in comparison to 2 x 200w enviros, although the yield would be better I cant afford to risk it with the space I have in my wardrobe - I need more head room or could go for those cool tubes but they are too expensive at the moment.

Yes by yield i mean just the buds no big leaves or unneccesary twigs. But with 6 plants if you veg for 4 weeks and then flower under a single 200w enviro then I reckon you'd be pushing to get 1/2oz per plant really, so thats about 3oz's altogether. I think you should get more light if you can, hps is the way to go really but good luck with your grow and let us know how you do... should be interesting! Btw in terms of quality of bud it's a knockout and so you don't use as much therefore 1oz of this stuff lasts much longer than 1oz of standard rubbish you get off the streets.

flowered 9 cindy99 under 400w of various fluros, yeilded about 3.5oz gie of take the odd smoke
it was by far my best grow if not totally exprimental! one thing i found, which may be totally strain specific is that topping and LST under envirolites works a treat

How much headroom do you have ?

My "drobe" is 6 foot 6 and the top foot is reserved for ventilation... but I grew for years in a 4 foot 6 high unventilated cupboard with a single 250 watt lamp

The total convected heat from a 250watt HPS is bound to be significantly less than two 200 watt enviros - you just need to have 7 to 9 inches between lamp and canopy.... it's the nature of the lamp.

Yeh I suppose it may work with 250hps... my drobe is 6ft tall but thers a shelff at the top n so I used this 2ft of headsapce for vegging plants, also my plants are very stretchy (maybe coz using enviros) and the are basically touchin the enviros afta 8 or 9wks of flowerin then they are chopped. If I get a more indica variety then possibly I cud use 250hps but then all that heat going up to my veggin section may make it too hot for my plants up ther! Neway av stopped growin for da moment coz av moved bak in2 parents house , n now am thinkin of findin a discrete outdoor spot 2 plant a couple of babies! Although i think i left too late for this yr wot do u rekon?

You would need to check out the "guerilla growing" forum.

Hey Compo,

I'm currently flowering my first grow with 2 x 125W of enviro in a 4ft high space, and getting what seems to be pretty good results, but am wondering if I could squeeze in a 250w HPS in the future. I'm guessing I'd need to be pretty on the ball with training/tieing or maybe go for a SCROG to use a HPS with this headroom? Am I right in thinking that from light to growing tip minimum would be 6inch with a 250W HPS?, factoring in the depth of the reflector, probably only leave me about 3' for plants and pots.............what do ya think?

Cheers,

Pixie

Edit to change 12W enviro to 125W enviro

6 inches is a teeny bit close .. I suppose I may get as close as 7 inches on occasions .. I use singed fan leaves as a guide to how close I can go.

I'm very fond of dished canopies, minimal reflectors and lighting from the side.

I still got 2 ounces off that 4 foot sativa pheno on the left.

I'm a bit negligent in not measuring the two LSTd plants in the middle - but they're propped up on pots... as was the un-LST's 3 foot indica pheno on the right ... so I reckon you might get away with 4 foot with good air movement. (Though as I have confessed I used to grow in 4 foot 6 with the reflector screwed to the "ceiling" and nothing but leaks and a draught )

Blimey, it's a jungle in there, expect to see tarzan swinging through any second.......So the secret is control of the canopy and airmovement between the lights and the canopy + decent exchange of course? I think I'll improve my skills on a couple more enviro grows, and then get a HPS for some king of concave SCROG from clone.......

Well slag em all you want i still pull over 9 oz dry off 3 plants in 11litre pots fed the biobizz range and thats using 4x200watt so in totall around 650-675 watts of light yes id get more from hps but then i dont like all these stories about lamps burning houses etc i see popping up , with cfl's they just stop working no mass fire evacuation needed.

Maybe one day ill go for hps but then it would have to be a 250watt and im fairly sure id get alot more from what i have now.

I bought my 250 watt lamps 12 years ago and not even a puff of smoke so far

I wonder if we'll ever know what causes the fires in grow houses, but I would hazard a guess it's cigarettes and cooking as usual ...
