I have been vegging under five 85watts cfl s which are around 6000k but my plants look weak to me, do you think they are ok for 8 plants. They are about 12cm s away from highest plant.



I have 8 fluoro tubes from philips sylvania and osram plantastar that I have not installed yet. Do you think they would be sufficient or shall i add another five of 85watts CFL with 2700k spectrum.

im not an expert but they seem small for being 44 days old...as for the light question, everyone will tell you more is better when it comes to cfls and flouros...especially if you are growing multiple plants

im assuming 85 watts is the equivlant, and then no you probably dont have enough for that number of plants, depending on how much space they take up. You want to have at
LEAST 5000 lumens per square foot, 10,000 is ideal. Hard to tell how big you room is but a 2x2 room should have at least 20,000-40,000 lumens. At day 44 plants should be about a foot tall imo.

Ok I bought 4 more 85 watts cfl s with 2700k yesterday, will be installing them on monday.
Installed two fluoros of sylvania, 6 more to go,
This means I will have 9 of 85watts CFL, and 8 of 36watt fluoro.
In total I have 45.000lumens from CFL s as they are 5000lumens each and 9600lumens from fluoros as they are 1200 each
Grand total of 54.600lumens for 80cm by 80cm grow room.

that's not true. I've seen people grow from start to finish in 16 ounce cups and yield 1 O per plant. True, a bigger pot will yield bigger plants. But, his plants are growing abnormally slow. Plus, i don't think you get rootbound that fast.

Looks like your lights need to be alot closer man! Should be no more than 2" away from tops...

The plants all look healthy... Just small. At day 44 you should be thinking about flowering. Toss up a couple pictures of the whole setup, it will make things alot easier to understand.

i think that the new light will do wonders. they seem healthy other wise. i would also put them on nutes asap if you havent done so already. ease em into it though. give them a 1/4 dose, and then work you way up to a full dose within a few waterings. good luck

Pretty obvious to me that your plants are not getting enough light. How far are your lights? They need to be within 2 inches of the leaves and such. Use Y adapters to get a better angle with them if you can. Other than being really small they look healthy.

all he needs is about 6 or 7 more of those cfls, hang them an inch or two away from the plants, then transplant them into 2 gallon pots. If you do transplant them make sure your careful and you give them water and root stimulator so they dont go into shock because they prob have allot of roots already growing. That should speed things up, and dont be afraid to add more lights especially during flowering since these lights arent that powerful.

If you are going to use cfls you can defiantly get a great yield. But you have to remember, put your lights up close to the plants, and I mean where they are nearly touching them. Mine actually touch the plants, and yes my plants do get tiny burns once a while at the tips of the fan leafs, but these fan leaves will be needed to be sacrificed in order for me to get anything worth writing home about. The closer the better. At 3 weeks some of mine where OVER a foot (I say 14 inches) and that's from seed, not a clone. While its true that the genetics and grow method may vary your success, they look very healthy but they sure should be bigger by now. Try it and show us what happens with some more pics in a week. Happy growing!

Question how many cfl did you use? Also in the past I've had cfls close to my plants and all it did was dry out the soil and the plants. Last time I kept it 4 inches away and my plants came out nice and big. I don't agree with that cfl sitting on top of the plant thing.
