Hello to everyone, A friend of mine grew legally CBD plants but the problem is the outrageously low THC limit of 0,2%. After he completed the harvest he sent samples of the buds for lab analysis and results came back showing 0,6% THC and 13% CBD. Now he cannot legally sell those flowers. He...

Hello to everyone :). Let's suppose hardness of water is 180 mg/l calcium carbonate + 20 mg/l magnesium carbonate. I visited this link: https://www.easy-grow.co.uk/amino-acids-hard-water/ where it's stated: "The best solution for hard water problems is to use a hard water nutrient formula...

After following Chip Green's advice,the issue was resolved Unit runs at 300 watt with minor dimming(thank you dude !!;)). Diyled, I reported the issue to them,they just said to send the driver back, no suggestions,nothing. Not only that, the order from them was supposed to arrive in 3-4...

Thank you very very much for your suggestions!! I am going to do it like you suggested and update!!

Hello to everyone. I have tried to wire this unit: https://invisiblesunled.co.uk/products/ish320-diy-mk3-horticultural-lighting-kit-powered-by-samsung-lm301h. It consists of 4 x ISH150 MK3 Samsung LM301H boards +Meanwell HLG 320H C2100A driver. By mistake they had sent me Meanwell HLG 240 H...

Hello to everyone. I am wondering if anyone has tried an autopot system with pots bigger than 7 gal. I have a fabric 15 gallon pot and was wondering if I could use a kit like this:https://www.autopot.co.uk/product/easy2go-kit/ along with a large enough tray to fit the 15 gal with success.

Yes, CMH are indeed efficient. I remember reading that they convert ~50%+ of their energy into light while for HPS numbers sit at ~27-30%. Considering BTU, doing the math 630W CMH equals the heat produced by 600w HPS+ a miniscule amount of 120 BTU extra. *Forgot to add that the ballast was remote.

Yeah, that is the thread I was talking about. My bad, thought test was done with DE bulb, not 2x315 CMH. Anecdotally, I replaced 1x600w HPS with a Lumatek DE CMH 630 in a previous grow and temps were a little bit higher after replacement. In this comparison...

Nice, in this case you harvest the whole plant at once. Try lowering the temps for the last few days :).

Nice, thank you for the link :). Yeah, that one looks nice indeed. And on a good offer from Amazon. Found this as well for something cheaper? Don't know if it would be at the same levels. It says "self-calibrating" on the description...

My guess is that you could take it down on day 70. Are all parts of the plant like that? You could cut the tops and leave the medium-lower parts mature, harvesting them at day ~80.

Anecdotally, Heisenberg Special from Mephisto Genetics won over many photoperiod strains in the past.

For Indica i liked a lot Blackberry Kush from Dutch Passion. Very unique high, beautiful deep purple buds. Plants are paradoxically "stretchers". Yield is medium. What size of tent? You could run up to 8 medium sized autos in 1x1 m tent aiming for 2 oz per plant. 2x315w CMH would do it some...

Nice, a friend of mine just germinated some Forum Stompers in pots with 15 gallons of organic soil :). After how many days from seed did you harvest the Stomper(s)?

I have used a diy Cree CXB 3590 B panel in the past and liked the results, 1g/watt is doable in organic soil. Liked their heat output as well.Supposedly the new Samsung chips are the shit producing really minimal amounts of heat. Going to find out soon :). Citizen chips are affordable and can...

It might seem a little bit strange and I don't know if it's only my experience. I have had hermies in the past from lightleaks in indoor grows. On the other hand I have also grown some plants in my balcony in the past. It's over a central road with many traffic lights. Their light does not reach...

Og Biowar supposedly works. Had seen some pics where aphids were toast after its use.

Use google searching "side by side grow. 630 CMH vs 1000 HPS". The first link that appears from another known growing forum will let you know how they compare :). I tested a Lumatek CMH 630 DE for a short time. I was pleased with the coverage and intensity. In fact it's a very strong bulb...

For 1x1 m you could try a 400w HPS vertical grow.

Once again thanks for the input! Do you think that something like that would be ok then? https://www.amazon.co.uk/Ecotechnics-Evolution-Carbon-Dioxide-Controller/dp/B00ELGBGG6/ref=sr_1_1?keywords=co2+controller&qid=1554162900&s=gateway&sr=8-1 They are the products most readily available where I...
